The Maxi Plasmid Kit Endotoxin Free was designed for plasmid DNA purification and endotoxin removal using pre-packed anion-exchange resin maxiprep columns to purify plasmid DNA from 200-1600 ml of cultured bacterial cells. TrueBlue Lysis Buffer (an optional color indicator) is included with the kit in order to prevent common handling errors, ensuring efficient cell lysis and neutralization. This endotoxin free plasmid kit uses a modified alkaline lysis method and RNase treatment to obtain clear cell lysate with minimal genomic DNA/RNA contaminants. Using an efficient gravity-flow procedure, plasmid DNA in the crude lysate is bound to the column and the contaminants are removed with the PW Buffer. The purified plasmid DNA is eluted by a high salt buffer and then precipitated with Isopropanol for desalting. The entire procedure can be completed in 2.5 hours without ultracentrifuges, HPLC or other toxic reagents and the purified plasmid DNA is suitable for Transfection, Sequencing Reactions, Ligation, PCR, and In-vitro Transcription, Microinjection, Restriction Enzyme Digestion and Gene Gun.

Quality Control:
The quality of the Plasmid Maxi Kit (Endotoxin Free) is tested on a lot-to-lot basis according to Geneaid's ISO-certified quality management system. Plasmid DNA from a 200 ml overnight E. coli (DH5?) culture, containing plasmid pBluescript (A600 > 2 U/ml) is purified using the Plasmid Maxi Kit. Following the purification process, a yield of more than 900 ?g is obtained and the A260/A280 ratio is between 1.8-2.0. The purified plasmid (1 µg) is used in EcoRI digestion, and analyzed by electrophoresis.
